MUVAIBLE PLATFORM FOR STERN END OF CAR FLUATSl.

specification of Letters Patent.

Application filed May 14,1917, Serial No.168,i78.

o all whom it may concern:

Be it known that 1, JOHN ML CHERRY, a citizen of the llnited States, residing at l l estfield, in the county of Union and State of New Jersey, have invented a new and useful improvement in a Movable Platform for the Stern End of CttI'-FlOtl/S,Of which the following is a. specification.

This invention relates broadly to gang tion is to provide a car float with a movable. platform as described, and to protect the entire platform by a root, one end of winch is pivotally supported and connected to the movable platform so that the two may be moved in unison to maintain at all times the proper distance betweenthe platform and the roof.

Still another object of the invention is to provide a counter-balancing mechanism for a platform and roof of this type so that the same may be easily adjusted as required.

These and other objects, together with at tendant advantages will be obvious as the invention becomes better understood by reference to the specification, and drawings forming a part thereof, throughout the several views of which like characters of reference have been used to indicate like parts.

Referring to the drawings,-

Figure l is a side elevation of a portion of a car float equipped with my improved platforms. 7

lFig. 2 is an end elevation. of the construction shown in Fig. l.

his. 3 is a plan view showing the pivotal mountings of my improved platforms.

ll ig. ll is a diagrammatic view showing the method of attaching the parts to the car float.

llt has heretofore been customary to equip car floats with stationary platforms over which the material carried by the cars was unloaded. These platforms have been objectionable for the reason that due to changes in the tidal condition of the waters in which the car float is operating, the plat form is not always at the proper elevation. To remedy this it has been necessary to provide planks or the. like which were laid from.

the wharf "to the car float. overcomes the diiliculties such constructions and provides a platform which is at all times protcctedfrom the weather, and is adjustable to meet the vary ing conditions of usage to which it. is. sub-. jected. 1

Referring more particularly to the draw- My invention ii'igs, if have shown a car float 1 of ordi} nary construction having mounted thereon a plurality of vertical standards 2 adapted. to support platforms l extending theentlre length of the car float at such a height above the same as to be substantially level with the car floors carried thereby. The standards: also support a roof 5 adapted to pm. tect both the contents of the cars, and the stevedores engaged in the unloadingflof the. same, from the weather. It will be apparcut that the roof and platformmay be constructed, and supported in any desired manner.

(in v the end of the float opposite that from which the cars pass onto the same and which for sake of. convenience will herein after. be designated the rear end of thefloat, are mounted movable platforms 6, hingedly supported by means of pivots to the platforms extending alongside of and. between the cars. i ls shown clearly in Fig. 3, the movable platforms have a separate connection with each of the unloading platforms, these connections lying at a point adjacent the door of the car lying nearest the rear end of the float. 'l he relative arrangement of parts is clearly shown in. Fig. l wherein a car is indicated in dotted lines in a p0sition to be unloaded. Adjacent the rear end of the car float are pairs of parallel uprights 8 connected by cross bars 9, and maintained in spaced relation by means of a cross brace it). Mounted on the cross braces 10 are pulleys l1 journaled on shafts 12 adapted to be driven by worm wheels 14. Extending beneath the brace 10 is a driving shaft 15 having its opposite ends journaled in hangers 16 carried by the uprights, and carrying a worm 17 adjacent each end in mesh with the worm wheels 14. For rotating the shaft 15 and the worm wheels 14:, the shaft is provided with a pulley 18 around which passes a hand rope or chain 19..

The platform is adjustably carried and Patented Dec. 11;, 191-7;

encountered in y tions, the roof 5 is provided with hinged bridges or gang planks.

portions 22 overlying the movable platform and connected thereto by links 24 so as to have a movement' n unlson with the platform. The entire construction may be braced in any, desired manner by suitable 'braces25. In some instances I have found it desirable to provide notches or sockets 26 in the platformiti to receive the hooks, ordinarily formed on the lower surfaces of small Such bridges or gang planks when used constitute a continuation of the platform while in any position, sothat thegoods maybe easily unloaded from the float.

While I have described the preferred form of my invention, it will be obvious that changes may bemadein the mechanical construction thereof Without departing from the scope of the appended claims.

lVhat I claim is 1. A car float'having a loading and unloading platform formed thereon so as to extend in substantially the plane of the car floors on the float, a movable platform secured thereto adjacent the doorway of the 'end car on the float, means for counterbalancing the weight of said movable platform, and means for adjusting said movable platform at will.

2. A car float having a loading and unloading platform formed thereon and overlying the floor so as to lie in substantially the plane of the floors of the cars on the float, a movable platform secured thereto, and means for adjusting said movable platform.

3. A car float having a loading and unloading platform formed thereon, a movable platform secured thereto means for adjusting said movable platforn'i, and an adjustable covering section for protecting said movable platform in all of its different adjusted positions.

4. A car float having a loading and unloading platforn'i formed thereon and ex tending longitudinally thereof. a roof protectin said platform, a movable platform secured to said first-mentioned platform. a hinged roof section, and means for adjusting said platform and roof section simultaneously.

5. A car float having a loading and unloading platform formed thereon and extending longitudinally thereof. a roof protectin said platform, a movable platform secured to said first-mentioned platform a hinged roof section means connecting said. movable platform and said roof section to cause the same to move in unison, means for moving the same, and means for counterbalancing the weight thereof.
